I could share the colors I used but they're subjective and mostly what I had on hand. The most important tips there are 1) watch the exploring colors videos by Vince Venturella to figure out how to properly lighten or darken colors. 2) get Vallejo Ice Yellow 3) get Vallejo Verdigris. These two colors will let you lighten most anything to a highlight without doing things like turning reds pink or purples into some pastel violet that doesn't highlight well.
